Answer:
A:linear function for both :
beach: y=-2x+100 (x=0, y=100)
dunes=5x+20 ( when x=0, y=20 (year1995)
B: after almost 11 years: it will be year 2006 and 2007 (after 11.429 years)
C: when the two rates of erosion are equal at the rate of 77 and almost 11 years
-2x+100=5x+20
-2x-5x=-100+20
-7x=-80
-80/-7=x
x=11.429
y=77.143
Given:
The faces on a number cube are labeled 1,2,2,3,4, and 5.
The number cube is rolled 114 times.
To find:
How many times would you expect the number 2 to appear?
Solution:
We have,
Total outcomes = 1,2,2,3,4, and 5.
Number of total outcomes = 6
Favorable outcomes = 2 and 2
Number of favorable outcomes = 2
The probability of getting 2 is:
Now, the expected number of times when 2 to appear is:
Therefore, the expected number of times is 38.
